I think this might be the answer since (a+b) equals 4, and ab= 3. I'm not sure.
a3 + b3
= (4)3+4(3)
= 12+12
= 24

Find the measure of x, then find the measure of each angle

stepladder [879]

First, you have to imagine that you cut the upper triangle. If you do that, then this is how the inner angles are added to 180°:

180° = 90° + (x/2) + (7x - 90°)

180° = x/2 + 7x

180° = x *(1/2 + 7)

180° = x*(15/2)

2/15 * 180° = x

24 = x

Angle A:

A= x/2

A = 24/2

A = 12°

Angle B:

B = 7x

B = 7*24

B = 168°

The two bottom angles are both worth 90°.

If z is an even integer which of the following expressions must represent an odd integer?

ad-work [718]

There is no choice on your list that must represent an odd integer.

If 'z' is an even integer, then (z-1) and (z+1) must both be odd integers.

Can somebody help me in this one :)

Answer:

A) f(x) = 6x + 14

Step-by-step explanation:

6(1) + 14 = 20

6 + 14 = 20

6(1.5) + 14 = 23

9 + 14 = 23

6(2) + 14 = 26

12 + 14 = 26

and so on...

Identify the number that does not belong with the other three. Explain your reasoning.

mojhsa [17]

Answer:

To identify which integer does not belong with the rest, we must first evaluate each.

Step-by-step explanation:

[25.6...] is already evaluated. Therefore, let's move on to Integer <em>b: </em> $\sqrt{x}$ , where is <em>x </em>is 48.

48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3

√48 = $\sqrt{2}$ * 2 * 2 * 2 * 3

We have 1 perfect sqaure: $\sqrt{2}$ * 2

When we multiply, we receive 2.

Therefore, 2 * $\sqrt{2 * 3}$

When -51/2 is relatively prime, we receive -25 1/2

Finally, the last integer is already simplified.

Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.
